how to show full layout in BottomSheetDialog with min and max height 350dp in android

My layout_xml code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

</RelativeLayout>
Java code:-
private void showCommentDailog()
{
Log.d(TAG,"showCommentDailog enter()");
commentDialog = new BottomSheetDialog(getContext());
View view = ((ProblemsDetailActivity) getActivity()).getLayoutInflater().inflate(R.layout.commentproblemscreen, null);
commentDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
commentProblemLV = (ListView)view.findViewById(R.id.commentProblemLV);
TextView commentProblemNotFoundTV = (TextView)view.findViewById(R.id.commentProblemNotFoundTV);
EditText commentEditTextET = (EditText) view.findViewById(R.id.commentEditTextET);
ImageButton commentSendTextIB = (ImageButton)view.findViewById(R.id.commentSendTextIB);
if(commentDialog.getWindow() != null) {
commentDialog.getWindow().setGravity(Gravity.BOTTOM);
}
//call the function to show list of previous work
commentDialog.setContentView(view);
commentDialog.setCanceledOnTouchOutside(true);
commentDialog.show();
final BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from((View) view.getParent());
bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
#Override
public void onStateChanged(#NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
commentDialog.dismiss();
}else{
if (newState != BottomSheetBehavior.STATE_EXPANDED) {
if(commentProblemLV != null && !listIsAtTop()){
bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
}
}
}
}
#Override
public void onSlide(#NonNull View bottomSheet, float slideOffset) {
}
});
}
This code does not show the full layout in bottomsheetDailog. Please correct my code as it shows the full layout in bottomsheetDialog.
I want to open full layout in half screen with BottomSheetDialog.
here I should be given my java code also for bottomSheetDialog.
bottomsheetdailog will apear on clickof comment ImageView.

Listview adapter not displaying list columns after closing of Dialog

Setup
In my app I have a section that creates rows of data to be saved in a database. Each row is built from a textbox, number box then "set" into a listview for display. Later on the user can open a "plan" created before and review the data.
I created a listview, a custom layout for the display line and figured out how to add/display each new row. However, when I perform the open, I create a dialog to display the list for plans, user selects on and the rows should display. They do not. I trace through the code and I see the arraylist for the adapter being populated and I call the notifydatasetchanged, but the main listview remains empty.
I am not using a customer adapter class, but just the Simple adapter.
This is the beginning of the Activity. I am still learning android coding so I tend to use generic names as I learn.
public class TrackItEqMainActivity extends AppCompatActivity {
/**
* ATTENTION: This was auto-generated to implement the App Indexing API.
* See https://g.co/AppIndexing/AndroidStudio for more information.
*/
private GoogleApiClient client;
public int rowCount = 1;
private static final String eTAG = "Exception";
final Context context = this;
// global variables needed for processing the add gaits display
**private ListView lstGaits;
private ListAdapter adapter;
private ArrayList<HashMap<String, String>> mylist;**
// *****
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i(eTAG, "onCreate Build");
setTitle(R.string.activityManagePlans);
setContentView(R.layout.activity_track_it_eq_build);
Toolbar mySecondaryToolbar = (Toolbar) findViewById(R.id.my_secondaryToolbar);
setSupportActionBar(mySecondaryToolbar);
setActivityBuildListeners();
// set the objects needed to handle the dynamic gaits list
ListView lstGaits = (ListView) findViewById(R.id.lstMyGaits);
mylist = new ArrayList<HashMap<String, String>>();
try {
adapter = new SimpleAdapter(this, mylist, R.layout.gaits_detail,
new String[] { "keyGait", "keyTime" }, new int[] {
R.id.txtdisplayGait, R.id.txtdisplayTime });
lstGaits.setAdapter(adapter);
} catch (Exception e) {
Log.i(eTAG, e.getMessage());
}
// ATTENTION: This was auto-generated to implement the App Indexing API.
// See https://g.co/AppIndexing/AndroidStudio for more information.
client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
}
SO when a user taps a new button a set of controls appear allowing to select a gait and enter a time. They then tap on the set button and in the set onClick, I add the data to the internal array and display the custom layout on the screen.
private Button.OnClickListener onClick_btnSet = new OnClickListener() {
#Override
public void onClick(View v) {
Spinner spinner = (Spinner) findViewById(R.id.spinner_gaits);
TextView textGait = (TextView) spinner.getSelectedView();
String gtResult = textGait.getText().toString();
TextView txtTime = (TextView) findViewById(R.id.txtSelected);
String tmeResult = txtTime.getText().toString();
buildDisplayLine(true,gtResult,tmeResult);
txtTime.setText("");
spinner.requestFocus();
}
};
The function that builds the line and adds to the array is this:
private void buildDisplayLine(boolean isNew, String gait, String time) {
HashMap<String, String> map2 = new HashMap<String, String>();
map2.put("keyGait",gait); // put the col data in
map2.put("keyTime", time); // put the col data in
mylist.add(map2);
if (isNew) {
((BaseAdapter) (adapter)).notifyDataSetChanged();
}
}
All that works although a strange side effect is that the list will not display if the number keypad is visible. When I clear it off the list appears.
Ifa use wants to look at or change a plan they tap the open button. IT display a dialog box that shows a list of plans. Tap on a plan and all the elements should display:
private final ThreadLocal<OnClickListener> onClick_btnOpen = new ThreadLocal<OnClickListener>() {
#Override
protected OnClickListener initialValue() {
return new OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.activity_track_it_eq_open_plan);
dialog.setTitle("Open Exercise Plan...");
Button diaCancelButton = (Button) dialog.findViewById(R.id.btnCancelOpen);
diaCancelButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
// get a list of files from the local app plans
final eqDatabaseService eqDB = new eqDatabaseService(context, 2);
ArrayList<HashMap<String,String>> allPlans = eqDB.getPlanList();
if (allPlans.isEmpty()) {
Toast toast = new Toast(context);
toast.setGravity(Gravity.TOP, 0, 0);
Toast.makeText(context, "No Files to open, Please create one!", Toast.LENGTH_LONG).show();
return;
}
ListView lvPlan = (ListView) dialog.findViewById(R.id.lvPlans);
try {
adapter = new SimpleAdapter(context, allPlans, R.layout.plans_columns,
new String[] { "keyName", "keyENum" }, new int[] {
R.id.txtPlanName, R.id.txtNumElements });
lvPlan.setAdapter(adapter);
} catch (Exception e) {
}
//********************************************************
lvPlan.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
TextView txtplan = (TextView) v.findViewById(R.id.txtPlanName);
String planName = txtplan.getText().toString();
List<eqSessions_dt> myPlan = eqDB.getCurrentPlan(planName);
clearGrid();
for (eqSessions_dt row : myPlan) {
buildDisplayLine(false, row.get_gait(),Integer.toString(row.get_time()));
}
((BaseAdapter)(adapter)).notifyDataSetChanged();
dialog.dismiss();
}
});
dialog.show();
}
};
}
};
I have played around with this, did look at other similar questions and answers, but didn't see anything that would explain why the notify would not work. I avoided doing a custom adapter, trying to keep this simple at first. What am I missing that stops the list from displaying. I see the arraylist being filled and all related objects are global to the activity. I'll keep playing around, but I hope otehr eyes see what I miss.

Android List View shows items, but text is empty

I am experiencing a very weird issue where I am unable to view any text/data, but it clearly shows the number of items in the list.
I have confirmed that dataList has data, and I am able to get the exact same string that I set after debugging.

EDIT: Screenshot added
EDIT2: Clarified parent fragment calling the adapter.
EDIT3: I did a temporary fix. Apparently the RelativeLayout and the Linear Layout in the AdapterXML were the cause of my misery. I'm not exactly sure why, though. I think it's the RelativeLayout and the LinearLayout somehow not displaying the text. Removing those two tags will display the texts in a linear fashion.

Try this

hide layout checkbox is checked android

I am trying to simply hide a linear layout if a checkbox is clicked. I have defined function and onClick attribute calls it which is also tested with toast but when I try hiding the layout, it doesn't do anything.
The layout.xml:
<CheckBox
android:id="#+id/cbguest"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.9"
android:onClick="itemClicked"
/>
In MainActivity.java
int[] i = {0};
public void itemClicked(View v) {
LinearLayout layoutguest1 = (LinearLayout) findViewById(R.id.guestlayout);
if (lns[0]%2 == 0) {
Toast.makeText(getApplicationContext(),"Visible", Toast.LENGTH_SHORT).show();
layoutguest1.setVisibility(View.VISIBLE);
lns[0]+=1;
}
if (lns[0]%2 != 0) {
layoutguest1.setVisibility(View.GONE);
Toast.makeText(getApplicationContext(),"Gone", Toast.LENGTH_SHORT).show();
lns[0]+=1;
}
}

boolean isChecked)
{
// TODO Auto-generated method stub

chkBox.setText("UnHide");

else

You should be using onCheckedChangeListener as I don't think it registers as an onClick- but an onCheck.

Custom ListView is not displayed

Following some tutorials, I managed to make a custom list.
But the whole screen is just a list
And now want to put the list below the form. And to make the whole screen make scroll along with the list (see the last item in the list, the form needs to rise)
The log (Toasty) says that the item was added, but nothing appears. I do not know if the problem is in how I add, or is the way I try to display

UPDATE
When I add an item in the list, nothing is shown. But after I click a TextEdit, and the virtual keyboard up, after typing some value, I close the keyboard, then the adapter.getView () is called and the list appears

I think I found your problem. Shouldn't the following code:
((ListView) findViewById(android.R.id.list)).setAdapter(listaAdapter);
Be:
((ListView) findViewById(R.id.list)).setAdapter(listaAdapter);
instead?
You are trying to find a default Android view, rather than the view that you have created, which means that you are not actually setting the adapter for your ListView.

I am not sure about that, but if you want the list to be scrollable with the activity, you should use ScrollView, and then check if you scroll the list or the view itself. Try it
You can also try to see with debugger if the item was actually added to the list. I hope you will find an error.

Found the solution
1) The adapter have 2 constructors, but just 1 with List<ItemVenda> itens, and it isn't called.
I fixed it.
2) To add an item on the list, I need to call adapter.add() and not adapter.getItens().add()`. I think this trigger others methods.
3) Finally, to take the scroll list, and apply the scroll across the screen, I need to increase the size of the list. Then I override the method adapter.add(), and calculate the new height of the list, and add android:scrollbars="none" on ListView
Thanks to all, especially to #Marek
